The implementation of safety training is conducted to provide knowledge on the importance of safety for its employees. However, the implementation of safety training requires many consumable things such as a lot of Portable Fire Extinguishers (PFE) that increase the operational cost and trigger the environmental pollution. This research aims to design a safety simulation based on VR (virtual reality) to provide an immersive experience for safety training and reduce the training costs. It was obtained that the application of VR technology requires two main devices namely HMD (Head-Mounted Display) and controller. Observations were conducted in the training of conventional safety and health at shipyards and training institutes. This research only simulates training on the use of PFE, fire drill, and risk observation on confined space from the ten topics of safety training based on observations that have been undertaken. Software such as Inventor, Microsoft Visual Studio, and Unity were used. After safety simulations was conducted, the result showed that safety training used VR can improve the work safety theory knowledge by 14.05%. Total cost of investment required for the development and equipment was IDR 24,043,667. The reduced cost of the safety training using VR was about IDR 193,889,154.88 or 68.13%.

Agar dapat bersaing di pasar global, perusahaan manufaktur harus secara terus menerus mengeliminasi waste yang terjadi dalam proses produksinya. Lean manufacturing merupakan salah satu pendekatan yang dapat digunakan untuk mengidentifikasi dan mengurangi waste di perusahaan. Dalam paper ini, pendekatan lean manufacturing digunakan untuk mengurangi waste di lantai produksi perusahaan manufaktur keramik. Adanya waste di lantai produksi menyebabkan keterlambatan dalam memenuhi permintaan pelanggan. Pendekatan value stream mapping (VSM) digunakan untuk menemukan permasalahan pada aliran produk dan informasi, sedangkan process activity mapping (PAM) digunakan untuk mengklasifikasikan aktivitas secara detail disetiap proses. Dari penerapan VSM dan PAM semua aktivitas di lantai produksi diklasifikasikan menjadi tiga kategori. Kategori pertama value-added activity dengan total waktu 186,1 menit, necessary non-value-added activities adalah 2.723,64 menit, dan non-value-added activity adalah 1.410,26 menit. Dari ketiga kategori kegiatan tersebut didapatkan rasio value-added activity sebesar 4,31%. Dengan menggunakan analisis Pareto diketahui, persentase non-value-added activity yang paling signifikan terjadi di proses drying, printing, dan firing. Metode Ishikawa digunakan untuk menemukan akar penyebab waktu non-value-added activity antara lain keterlambatan penggantian komponen, Kurangnya pelatihan operator, tidak adanya pemeriksaan berkala kurangnya kesadaran operator. Metode 5W1H menemukan usulan perbaikan yang sesuai dengan menambahkan tugas kepada operator proses glazing. Beban kerja operator dihitung ulang menggunakan metode full-time equivalent (FTE) untuk menentukan jumlah operator. Hasil penelitian menunjukkan bahwa waktu value-added activity meningkat 3,57% menjadi 192,27 menit, dan necessary nonvalue-added activitiy menurun 1,32% menjadi 2.759,70 menit. Namun, waktu non-value-added activity mengalami penurunan sebesar 3,03% menjadi 1.367,56 menit dengan rasio value-added activity sebesar 4,46%.

“…Among many benefits, there are two significant cross-cutting advantages in ship automation: the crew diminution and the hazards and risks reduction of the people in general and the ship itself [ 1 ]. The first implies a significant reduction in ship operating costs directly [ 2 ]. Indirectly, it would entail aspects related to improving the conditions of workers in general terms (training, social security, the possibility of oversizing the workforce, …) [ 3 ].…”

Systems engineering plays a key role in the naval sector, focusing on how to design, integrate, and manage complex systems throughout their life cycle; it is therefore difficult to conceive functional warships without it. To this end, specialized information systems for logistical support and the sustainability of material solutions are essential to ensure proper provisioning and to know the operational status of the frigate. However, based on an architecture composed of a set of logistics applications, this information system may require highly qualified operators with a deep knowledge of the behavior of onboard systems to manage it properly. In this regard, failure detection systems have been postulated as one of the main cutting-edge methods to address the challenge, employing intelligent techniques for observing anomalies in the normal behavior of systems without the need for expert knowledge. In this paper, the study is concerned to the scope of the Spanish navy, where a complex information system structure is responsible for ensuring the correct maintenance and provisioning of the vessels. In such context, we hereby suggest a comparison between different one-class techniques, such as statistical models, geometric boundaries, or dimensional reduction to face anomaly detection in specific subsystems of a warship, with the prospect of applying it to the whole ship.
